PRINTING-PRESS.

State of Missouri, have invented certain new and useful Improvements in Printing- -P resses, of which the following is a specifi-' cation.

This invention relates to printing presses and has for its object to produce a machine for printing both sides of a Web of paper and creasing such printed Web in parallel lines in opposite directions so that it may be collapsed along such hnes like an accordion,

to book form with alternate folds forming the hinge points for the leaves. A further object is to produce means for severing the printed Web coincidentally with certain of said creases so that the books shall contain an equal number of leaves.

I A further object is to produce a pair of endless conveyors, one equipped with a seetional bed adapted to carry the type or printing plates and the other with frames for printing the border lines and-carrying when desired, cross bars for printing dashes,

, bed sections.

headings, lines or page embellishments.

A further object is to produce means for separately inking the type orprinting plates and the border, in different colors if desired.

lVith these general objects in view the in vention consists in certain novel and peculiar features of construction and organiza tion as hereinafterappear; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which--- Figure l isa side View of aprinting press embodying my invention.

is a detail perspective view of the movable cutting blade and the swing frame carrying the same.

In the said drawings, 1 indicates a suitable frame.

2 indicates a drive belt-Wheel. mounted less chains 7 extending longitudinally of the machine and parallel with each other to a pair of sprocket wheels 8 on a shaft 8 suitably ournaledas hereinafter explained, wheels 6 being also connected by parallel chains 9 to similanpair of sprocket wheels 10 on shaft 8*.

11 indicates a series of bed plates provided with trunuions 12 journaled in opposite links oit' chain 7, the frontedge of each bed plate being provided with a plu-' rality of arc-shaped passages l2 struck from the lower front corner of the plate and receiving slidingly arcshaped arms 13'projecting rearwardly and downwardly from the upper rear corners of the adjacent plate, as shown clearly in Figs. 9 and 10, this arrangement connecting the plates reliably together without interfering with the relative change of position which occurs as the carrying chains 7' round the sprocket wheels 5 and S, the said bed plates turning pivotally to some extenton their trunnions 12 asthey round said sprocket wheels'witli said chains.

1=l indicates two series of printing plates upon the bed plates or sections 11,- a pair of said printing plates being arranged inaline- 'ment with each other and transversely across each bed plate or section, the series of printing plates at one side of the longitudinal center of the convey-er being adapted to print one side of a webof paper hereinafter referred to, and the other series the opposite side of such-web, the printing plates of each series being spaced slight distance apart. The tWo series of plates are also plates Whether compose ,plates may be the head ends The printing plates are of uniform length andwidth-though in practice some of them spaced apart and at equal distances from the longitudinal center of the conveyor, the inner ends of the plates being preferably the head ends though the outer ends of said if desired.

will consist of two sections as shown in Figs.

5 and 6, and in some cases more than two sections, but in any event the length of the of one or a pluralit-y of sections, will be the same.

indicates rectangular border frames adapted to snugly inclose the printing plates and rest upon the. underlying bed the plates or sections when] traveling in plane of the upper strands of the conve the said frames being provided with b not ribs 16 to print borders around the imprints madeby the printing plates 17- indicates transverse ribs which may he employed singly or in multiple to connect opposite ribs of the border frame between i sections of a printing plate as indicated in one or more of said trunnions is provnci hereinafter appears.

shaped so as to bridge over or under a 5 and 6, these ribs 17 being adapted to print-dashes, headings; etc. or they may be employed in such form and in such proportion as to print symbols or embellishments of any kind.

Each 1a is provided cent-rally of its ends with outwardly projecting step-shaped trunnions 18 said trunnions being stepthus avoid chains 7, and said trunnions pii otally engage certain links of chains 9,

sectional bed and the printing plates 14 carried thereby extend over and in engageu'ient 'with an inking mechanism 20 of any suitable The lower strands of cha1n 9 andtype. hence the border plates 15 are permitted to sag below the plane of the lower strands of chains 7 so as tospace the printing plates and border frames apart'to permit them to be separately inked, this being especially desirable where ink of two different color; is

- to be employed, 21 representing the inking mechanism for'the said border frames. To maintain the border frames in proper operative relation to-each other when spaced from and not supple-ted by the sections 11 of the bed, they are connected together in the same manner that said bed sections are connected, that is to say each borderv frame is provided with arc-shaped openings 22 for the reception. of correspondingly shaped arms 23 projecting rearwardly from the adjacent bed-section.

From the foregoing. it will be apparent thatvafter. the printing platesand border frames are separated and individually inked by inking mechanisms 20 and :2 respectively, they will reassume their original relation as they-pass upwardly around sprocket wheels 10 and thus be prepared in their forward travel to sinmltaneously perform their printing function r 24: is a transverse shaft arranged horizontally and arranged in frame 1 between the upper and lower strands of the conveyers and mounted "rigidly on said shaft is a roller 25 having its topmost point in the plane or the underside of the upper strands of chains 7 and 9 and the bed plates or sections to provide resistance to downward movement of said parts when the paper web is pressed down upon the printing plates and border frames by means of the roller 26 overlying roller 25 and likewise mountedon I a transverse shaft 27, provided with circular cams 28 journaled in hearing boxes 20 slidably mounted in vertical slots 30 in the frame. Said bearing boxes are equipped with upwardly projecting externally threaded circular flanges engaged by flanged nuts 32, and extending through said nuts and the overlying parts of the frame are adjusting'screws 33 said screws being equipped at their lower ends with heads 34; swiveled in said nuts and at their upper ends with heads 35 by which they are turned for the purpose of vertically adjusting boxes 29.

36 are nuts mounted on screws 33and between said nuts and heads 35 the screws are provided with rear-wardly projecting arms,

37 connected by retractile springs 38 with levers 39' of shaft 27 the tendency of the springs 38 being to hold the levers 39 yieldingly elevated and the circular cams 38 in such position that shafts 27 are, depressed to hold roller 26 likewise depressed. For 'the' purpose of raising roller 36 to an inoperative position the levers 39 are provided with a pivotall depending rod 40 connected attheir lower ends by a cross rod 41', connected by a link 42 to a treadle or foot-lever 43 fulcrumed on a bracket 44 hearing a fixed or rigid relation with frame 1.. Mounted upon the ends of shafts 24 and 27 are intermeshing gearwheels'lfi and 46 respectively'and cngaging gear wheels 45 are idler'gear pinions 47 journaled upon stub-shafts 48 projecting outward from the sides of frame lysaid gear wheels 48 meshing with drive gears 4 to be operated by thesamc and hence mpart rotation to rollers 25 and 26 as indicated by the arrows in Fig 1, it being noticed in this connection that to reliably space rollers 25 and 26 apart to properly accommodate the passage between them of the superposed printing bed plates or sections, printing plates, border frames, gaging spacing bands-49 and 50 are secured on the ends of said rollers respectively.

a traveling pin to operate the movable cutting-blade and cause the same to cooperate with the stationary blade in'severing the paper web along certainof its crease lines.

6. A printing press, comprising a suitable frame, a pair of superposed driven rollers, an endless conveyor having its upper strand interposed between said rollers and embodying bed-plate sections p'ivotally linked together, a pair of printing plates arranged end to end upon each bed-plate section and transversely of the conveyor, a

shaft suitably journaled and equipped with a paper roll above one of the printing plates rearward of said pair of rollers, a second pair of driven rollers fiflll'iill'd of and parallel with the first-namcd pair and adapted to receive the paper web extending forwardly from the roll after it has passed between the upper roller of the first-named pair and the underlying printing plates, and a guide at the front end of the frame for engagement by the paper web after it has passed between said second pair of rollers to cause the-paper web to travel laterally and then rcarwardly in the rerdcal plane of the other series of printing plates to permit the paper to extend thence rearwardly over and around the upper roller of said firstnamed pair of rollers and forwardly between the same and said second series of printing plates and then forwardly between shaft suitably journaled and equipped witha paper roll in the vertical plane of one of the series of printlng plates and rearward said assess 52 of printing paper. the paper web extending downwardly and forwardly under roller 26 vertically over the left hand. series of printing plates and border frames, it being noticed that the width of the paper is slightly less than half the length of the transversely arranged bed plates or sections. After passing under roller 26, the paper web extends forwardly and between a pair of horizontal rolls and 5d journaled in the frame 1 and equipped at their ends with interineshing gear wheels and 56 respectively, the last-nan'ied gear wheels being engaged by idler gear wheels 57 meshing with drive gears d and journaled on-stub shafts 58 projecting out ardly from the frame. From rolls 53 and 5d. the paper web extends under the left hand arm of the J-shaped paper guide frame 59 secured to the frame 1 at its ends and braced'at its apeX from said frame by a brace 60. The paper guide frame 59 is preferably pitched upwardly toward its apex end and its arms are disposed at angles of forty-five degrees to the longitudinal center of the machine and atninety degrees to each other so that the paper web shall extend upward and over-said. arm transversely of the machine and then over and under the companion arm, and thence extend upwardly and rearwardly over and around and under roller 26, and thence forwardly and again between rolls 53 and and from the latter downwardly between a pair of superposed rolls 61 and a pair of similar rolls 62, both sets of rolls being journaled at opposite ends in frame 1, and ba 7 62 secured on tie-rods 62 and 6: connecting the sides of the frame. )in oscillatory creaser is also journaled in frame 1 ant bar 69 centrally between d sets of roll and $32 and "in tructed asfollow is a pair of pat waidly projecting un frame and l 3 jecting angl pair of th 4 V such form and t an creaser is oscillated, extendir through the ClL respect the resu at tllai iuien 1 press the paper seibet ween the-n1,

position is reve sed it passes over the right-hand series of printing plates and border frames in order that such series of y betii'een rolls ill. and rolls 52,

mechanism being constructed as follows:--

70 indicates a standard erected rigidly upon one side of frame 1 and pivoted to the upper end of the same is aswing frame adapted to swing in a plane parallel with the sides of frame 1, and provided at its upper end with an inwardly projecting arm 72 terminating in adepending portion 73. The lower end of arm 71 is provided with a forwardly projecting arm T l having a laterally projecting arm 7 f which in length is about equal to the width of the paper web and occupies the same vertical plane as the creased portion of the web, the inner end of arm 74? being connectedto arms 71 and 74 by the oblique brace 74, it being noted that the depending portion 73 occupies the path of travel of the trunnion extension 19 so as to be struck and swung forward by said trunnion extension. The swing frame is equipped with a cutting blade 75 disposed rearward of the paper web and below rolls 69, and to steady said frame and limit the re: ward swing thereof, a cross rod 76 is disposed below the blade and carried by frame 1 and bar 62. At the opposite side of the paper web and also car ried by frame 1 is a stationary cutting blade 77 which blade is preferably disposed in such position with respect to cutting blade "?5 and to the paper web that it will cooperate with the former, each time it is swung forward, in severing the pa per along one of its crease or fold lir lit will thus be seen that the machine takes the paper from the rear and prints both sides of it, in two colors if desireth'and eventually creases it and then FGTOIS it predetermined lengths so that the creased severed portions may be collapsed into "the form of booklets.

Should it be desired to vary the number of pa es in the booklets it will he nec 1" to increase the number of bed plates or tions, printing plates and border frames and to correspondingly increase the length of the chains, it being also necessary to adjust sprocket wheels 8 and 10 rearward on the frame, and in order that this may be conveniently done the shaft 8 of said sprocket wheels, is journaled in brackets T9 slidably n'munted on the sides of frame 1, said brack ets being equipped with set screwsSO for engagen'ient with the sides of said frame to guard against accidental sliding i'i'iovement of the brackets.

From the above description it will be apentrees pair and adapted to receive the paper Web extending forwardly from the roller after it has passed between the upper roller of the firstnamed pair and the underlying printing plates, a'guideat the front end of' the frame for engagement by the paper web,

afterit has passed between said second pair of rollers to cause the paper web to travel laterally and then rearwardly in the vertical 7 plane of the other series of printing plates to wardly between the same and said second permit the paper to extend thence rearwardl over and around the upper roller of said rst-named pair of rollers and forseries of printing plates-and then forwardly between the second pair of rollers, two pairs of parallel rolls suitably journaled and arranged at opposite sides of the paper after it has passed the second time between the said second pair of rollers, and an oscillatory creaser for pressing the paper simultaneously in opposite directions between the said pairs of journaled rolls to crease said paper from one side margin to the other in parallel lines in opposite directions;

In testimony whereof I afiix my signature, in the presence of two witnesses.
